I did not want to destroy a listener's ranking, especially be it a personal one. My 'heroes' have not to be the greatest among their professions. Speaking of some kind of greatness makes presumptions and needs criteria, and speaking of my personal favorites uses other 'presumpteria'. So, if the music of a given composer overwhelms me, I may feel for him (or her) as would she / he be a giant. This is very okay.
But my feelings are feelings and not a viewpoint. My feelings can coexist with the viewpoint of other composers to be greater, since my feelings are nearer to me then other people's thoughts, arguments, and viewpoints.

Formal development has been meant as a historical process which you can not immediately hear while listening to a piece of music. If you are trained in historical evolvements, you will be able to recognise some elements, and then it is possible that your emotions by such intellectual knowing get deeper then before.
Dramatic arcs on the other hand are at first hand of emotional quality. You can experience them rather than reflecting on them.

The last five or six or seven symphonies of Mozart show such dramatic arcs and in this way they are emotionally deeper than his symphonies before.
Chopin's piano concertos show lacks while the construction of such arcs. If you listen attentively you will remark it. But this is of course no 'must do'!
